Abstract: | Fillenbaum (Journal of Personality and Social Psychology, 1966, 4, 532–537; Fillenbaum & Frey, Journal of Personality, 1970, 38, 43–51) has proposed that a relatively large number of subjects within certain experiments will adopt a faithful subject role, that is, they will intentionally avoid basing their behavior on any suspicions they may have regarding the experimenter's hypothesis. However, examination of the studies on which this conclusion was based casts doubt on whether Fillenbaum's subjects were truly faithful or whether they may have become aware of the nature of the deception after all opportunity for awareness to influence their responses had passed. To test this hypothesis, awareness measures were administered to subjects either before they took an incidental learning test or (as in Fillenbaum's studies) after the test. As predicted, fewer subjects were classified as faithful in the first condition than in the second. It was concluded that, in fact, very few if any subjects are actively faithful. Discussion also concerned the problems associated with role analyses of subject behavior. |
